SHlNGLE-SAWING MACHINE.

SPECIFICATION forming part of Letters Patent No. 779,260, dated January 3, 1905.

Application filed April 11, 1904:. Serial No. 202,673.

To all whom it may concern: 1

Be it known that I, LEON BRAULT, a citizen of the United States, residing at Wausaukee,

in the county of Marinette and State of VVisconsin, have invented new and useful Improvements in Shingle-Sawing Machines, of which the following is a specification.

My invention relates to a spalt-ejector for shingle-sawing machines; and the object of my invention is to provide a ready means of ejecting the spalt without stopping the machine.

In the accompanying drawings, Figure 1 is a plan vi ew, Fig. 2 a side view, and Fig. 3 an end view, of my invention.

A represents the frame, B the tip-table, and G the saw. of a shingle-sawing machine.

D represents the sliding dog, and E represents the stationary dog.

F represents the carriage, and G one of the carriage-tracks.

The dogs grip the shingle-block, the carriage carries it forward upon the saw, then back over the tip-table. The dogs then release the block, and the tip-table operates to tilt the block in the opposite direction before it is again gripped by the dogs and carried forward. The operator stands at the side of the track G and usually feeds the block when the carriage is forward over the saw. The drawings illustrate an automatic power-feed machine. In describing my invention it will be considered that the carriage moves forward upon the saw and rearward in returning. Fig. 3 will therefore be considered a view of the rear end of the machine.

The object of my invention is to eject the spalt from the rear end of the machine, so that in the next forward movement of the carriage a new block may be fed upon the saw.

H represents a gate sliding vertically in ways I I at the rear of the carriage and operated by the crank-arms J J, which are keyed to the shaft K. The shaft K is properly journaled in journal-boxes 70 is k, mounted on the carriage, and carries the crank-arm L, provided with an outwardly-extending traveler Z, which travels just above the track G.

M represents an incline-plate controlled and the dotted position M, Fig. 3, out of action. I

The gate H normally forms the rear bearing of the entire shingle -block as it is forced against the saw. When the operator desires to eject a spalt, he raises the handle from the position N to the position N, Fig. 8. The in- Cline-plate M will then be at the position shown in Figs. 1 and 2 upon the track G. As the carriage returns rearward the traveler Z travels up the incline M, thereby revolving the shaft K rearward and also revolving the crank-arms J J. Each crank-arm J is provided with jaws j j. which engage a pin it, attached to the gate H, and afford enough reciprocation so that the upward revolution of the crank-arm J raises the gate perpendicularly. The gate is raised while the carriage is returning rearward, and the momentum of the spalt is sufiicient when the carriage stops to throw it back beneath the gate off from the tip-table. If this does not occur, the gate may be dropped in front of the spalt at the next forward movement of the carriage, a new block fed to the machine over the saw, and upon the next return of the carriage the closed gate will push the spalt rearward from the tip-table. The operator holds the handle N up until the spalt is ejected, then releases the handle, when its weight will revolve the shaft 0 and carry the incline-plate M to the position M out of action. The shaft'O is suitably journaled to the frame at 0 0, and the plate M may be set at any position longitudinally of the shaft by means of the set-screw m.

The gate drops by gravity; but to prevent clogging or sticking on the ways a central springP is provided. lVhen the gate is raised, it compresses the spring, which pushes clownwardly the moment the gate is released.

Q, represents aspring-hub keyed to the shaft K and carrying the spring S. When the handle N is raised, the revolution of the shaft brings the spring down, so that its point S springs against the bracket R upon the rear end of the sliding dog D. WVhen the dog spreads to release the spalt, the end S springs down just below the top of the bracket R, engages the inner edge of the bracket, and holds the dog open, so that it cannot grip the spalt while being ejected. WVhen the handle N is dropped, the spring S is raised out of action.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a shingle-machine, a traveling frame, gripping means thereon, a removable backing means for the block, and means for lifting the same out of position for discharging spalts.

2. In a shingle-machine, the combination with a suitable frame, of means for forcing a block against a cutting device comprising a traveling frame and a vertically-moving gate carried thereby, the said gate normally forcing the shingle block against the cutting means, and means for shifting the gate to permit the discharge of spalts.

8. In a shingle-machine, the combination with asuitable frame,a sliding member mounted thereon, a vertical-moving gate for forcing the shingle-block forwardly in the machine, means for raising or lowering the gate, and hand-operated means capable of being brought into position to operate said gate.

4. In a shingle-sawing machine, the combination of a frame, a sliding block-carrying member mounted thereon, a tip-table mounted adjacent thereto, a vertically-movable gate carried by the moving member, and a rockshaft for operating the said gate.

5. In a shingle-sawing machine, a frame, a block-handling mechanism movably mounted therein comprisinga table, grippers for holding the said block, and a gate for forcing the block-forward, pivotally-mounted arms engaging the said gate, a shaft carrying said arms and a trip mechanism for rocking the shaft and shifting the gate at the proper time for discharging spalts from the machine.

6. A shingle-sawing machine comprising a frame, a block-carrying mechanism mounted therein, a block-engaging gate movably mounted upon said carrying mechanism, a rock-shaft connected with the said gate, and a trip mechanism capable of movement into and out of engagement with the said shaft, the gate being lifted for discharging spalts from the machine when the tripping mechanism is brought into'engagement With the shaft.

7. A block-controlling mechanism for shingle-sawing machines comprising a tip-table, a movable frame above the table, grippers, an abutment-gate mounted adjacent thereto, and means for lifting the abutment-gate to permit of the ejection of spalts at the rear of the machine.

8. In a shingle-sawing machine, means for carrying shingle-blocks forward against a cutting device, comprising a sliding frame, atiptable for supporting the said blocks and an abutment-gate having a sliding engagement with said frame near the rear end thereof, a rock-shaft for lifting the said gate, and a removable Wedge-block or inclined plane for tripping the said rock-shaft, and lifting the abutmentgate from behind the spalts permitting of their ejectment at the rear of the machine.

9. A block-han dling mechanism for shinglesawing machines comprising a sliding frame, a fixed and a movable gripper carried by the said frame, an abutment-gate at one end of the frame, a rock-shaft for lifting the gateJa spring-arm projecting from said shaft, means for rocking the shaft to lift the abutmentgate, the spring-arm at the same time being moved into the path of the movable dog for holding the same out of engaging position while spalts are ejected beneath the abutmentgate.

10. A block-handling mechanism for shingle-machines comprising a moving frame, grippers carried thereby, an abutment-gate mounted adjacent to the grippers,'a rock-shaft for elevating the gate, a spring for forcing the gate downwardly, a crank carried by the said rock-shaft, a movable wedge-block for engaging the said crank and thereby rocking the shaft, and a weighted arm for moving the wedge-block into and out of operative position.

11. A block-handling mechanism for shinglemachines, comprising a sliding frame, grippers thereon, an abutment-gate, a rockshaft for operating the said gate, a crank-arm carried by said shaft, a wedge-block capable of movement into and out of engagement with said crank-arm, a shaft carrying the said wedge-block, bearings carrying said shaft, and means for ad j ustably securing the Wedgeblock at suitable points upon said shaft, the block being moved into and out of operative position upon rocking the said shaft.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

LEON BRAULT.
